Sony FE 50mm F/1.8 SEL50F18F

This Sony prime delivers a standard 50mm focal length for full-frame E-mount cameras. That length suits portraits, street photography and everyday pictures, with a view that often feels natural. Sony introduced it in 2016, and it remains in production today.

The bright f/1.8 aperture and light weight make it an easy lens to keep on the camera. The main trade-off is the fixed focal length, so you frame by moving yourself rather than turning a zoom ring. In return you get a small, bright package, and owners give up built-in stabilisation and sealing.

The lens weighs 6.6 oz (186 g) and runs 2.34 in (59.5 mm) long with a 2.7 in (68.6 mm) body. That size makes it barely noticeable on the camera or in a small bag. Screw-in filters attach directly to the 49mm thread. Our physical score is 64.

On a full-frame sensor, 50mm gives a useful middle ground between wide views and telephoto framing. Stand back for half-length portraits, or move closer for a head-and-shoulders frame. The same view handles street scenes, shop fronts and dinners. Tight interiors may require more room than you have available.

At f/1.8 the lens passes much more light than slower designs, so in dim rooms you can keep shutter speeds up and ISO down. Evening interiors and candlelit tables stay within reach. It also throws the background out of focus, separating a portrait subject from a busy street behind.

Close focusing reaches 1.5 ft (45 cm), measured from the sensor. That is useful for a plate of food, flowers or other tabletop subjects. Move farther back for portraits if you want a more comfortable gap and a less exaggerated perspective.

Wide open the depth of field runs thin, so close portraits need careful focus on the eyes. Stop down when you want more of a group shot in focus. This combination of a bright aperture and a natural view defines the lens, and our optics score for it is 81.

There is no image stabilisation in this lens. A suitable shutter speed and a steady hold help control camera shake. The 50mm focal length is less demanding than a long telephoto, but slow handheld exposures can still blur. In-body stabilisation can help where fitted; otherwise brace the camera or use firm support as the light falls.

There is no weather sealing either, so keep the lens out of rain and heavy dust. The front element also lacks a fluorine coating, so fingerprints and water spots call for ordinary lens cleaning.

The optical formula is simple: 6 elements in 5 groups, including an aspherical element. Its specially shaped surface helps correct optical faults such as distortion, which can curve straight edges in doorways or buildings. The whole lens stays light, so it is easy to carry all day.
